The opt_opencl_bench function copied the device name using strcpy without checking if the source string was larger.
This patch fixes this by replacing the strcpy with av_strlcpy, with the string copy size capped to the destination buffer size.

av_image_fill_pointers always aligns the palette, but the padding
bytes don't (and can't) get initialized in av_image_copy.
Thus initialize them in av_image_alloc.
This fixes 'Syscall param write(buf) points to uninitialised byte(s)'
valgrind warnings.

Since len is an unsigned int, the comparison is currently treated as
unsigned and thus ignores all errors from avio_read.
Thus cast len to int, which is unproblematic, because at that point len
is between 0 and 4.
This fixes 'Conditional jump or move depends on uninitialised value'
valgrind warnings in is_tag.

In init_planes p->xblen and p->yblen are set to:
p->xblen = s->plane[0].xblen >> s->chroma_x_shift;
p->yblen = s->plane[0].yblen >> s->chroma_y_shift;
These are later used as block_w and block_h arguments of
s->vdsp.emulated_edge_mc. If one of them is 0 it triggers an av_assert2
in emulated_edge_mc:
av_assert2(start_x < end_x && block_w > 0);
av_assert2(start_y < end_y && block_h > 0);

If bytes is large enough, bytes*8 can overflow and become negative.
In that case 'bufsize -= bytes*8' causes bufsize to increase instead of
decrease.
